Each district, with the assistance of the local police and fire departments, shall annually review and update as appropriate the plan. At the beginning of each school year, students at each school shall be instructed as to the plan that is developed.

The  police chief or a designee shall visit each school at least 2 times each year for the purpose of conducting critical incident drills. These drills shall be conducted without advance warning to the school personnel other than the person in charge of the school at the time.”
